Grano de Oro - Lima & Palomino Islands

Prony Bay has a quiet magic, and Le Sournois is arguably its brightest spark. We love dropping onto this reef's edge, knowing we’re about to be swallowed by fish. The site caps out at around 18 metres, but the real action happens in the shallower stretches, 6 to 10 metres, where the light plays off the coral heads. Schools of fusiliers are so thick here, they often dim the sunlight for a moment as they swirl past. It’s not just the sheer volume of fish, though; it’s the variety. We’ve finned past honeycomb groupers lurking in crevices, watched ornate pitar venus clams filter feed, and occasionally, if you’re lucky, you might spot a dugong grazing peacefully in the seagrass beds nearby – a rare, gentle encounter. Look closely, and you’ll find brown-banded pipefish camouflaged against the coral. Le Sournois feels like a busy neighbourhood, a constant hum of activity. It’s a site that rewards slow diving, allowing you to absorb the constant motion.
